Answer:

Domain of f(x) = 2/7x - 2: (-∞, ∞)

Range of f(x) = 2/7x - 2: (-∞, ∞)

Domain of f(x) = |x + 3| - 1: (-∞, ∞)

Range of f(x) = |x + 3| - 1: [-1, ∞)

Domain of f(x) = -5x + 4: (-∞, ∞)

Range of f(x) = -5x + 4: (-∞, ∞)

Step-by-step explanation:

We can use a graphing calculator to find the graphs.

Domain is the set of all x-values that can be inputted into function <em>x</em>.

Range is the set of all y-values that can be outputted from function <em>x</em>.

Edmund purchased a computer for $1,800 on a payment plan (month zero). Three months after he purchased the computer, his balance
trapecia [35]

Answer:

Well I can't make a table but I can explain the answer.

Step-by-step explanation:

So you have $1,800 on a payment plan.  In three months, the balance is 1,350.  So 1,800-1,350=450.  This means he paid $450 in three months.  450/3 is 150.  He pays $150 a month.  Then 2 months later, (5 months after purchase) he has balance is $1,050.  1,350-1,050=300.  300/2=150.  Further evidence of the fact that he pays 150 dollars a month.  This means that the 6th month, he will have $900 dollars left on the payment.  7th month... $850, 8th month... $600, 9th month... $450, 10th month... 300 dollars, 11th month... 150, and 12 month he will have paid off all of his computer.  Hope it helps, sorry it is so long.  Have a great day!  :D

The value of y varies directly as the square of x and y=36 when x=3. What is y when x=4?
MissTica

Answer: y = 64

Step-by-step explanation:

y <> x² ----------------------- 1

y = kx² ----------------------- 2

36 = 3²k

36 = 9k

K = 36/9

= 4.

To find y when x = 4, we substitute for x in equation 2

y = kx²

y = 4²k

y = 16 x 4

y = 64
